GEOGRAPHIC SETTING: Begaysoils occuron fan remnants, structural benches and broad mesa tops <br />at elevations of 4,700 to 7,400 feet. Slopes are 0 to 30 percent. These soils formed in deep eolian <br />deposits and alluvium from sedimentary rocks. The climate is semiarid and the average annual <br />precipitation ranges from 8 to 14 inches. The mean annual temperature is 44 to 55 degrees F. The <br />mean summer temperature is 59 to 63 degrees F. and the freeze-free period ranges from 110 to 175 <br />days. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the the competing Moepitz soils. Anasazi soils <br />have a calcic horizon and have a lithic contact at depths of 20 to 40 inches. Aneth soils do not have <br />Iambic horizons and have a sandy particle size control section. Sogzie soils have calcic horizons. <br />DRAINAGE AND PERMEABILITY: Well drained; very slow to medium runoff; moderately rapid <br />permeability. <br />USE AND VEGETATION: Used only as rangeland. Potential vegetation is needleandthread, big <br />sagebrush, blue grama, Indian ricegrass. <br />DISTRIBUTION AND EXTENT: Southeastern Utah and northwestern Colorado. Begay soils are <br />moderately extensive. MLRA 34, 35 and 48A. <br />MLRA OFFICE RESPONSIBLE: Phoenix, Arizona <br />SERIES ESTABLISHED: San Juan County, Utah, 1976. <br />REMARKS: These soils have been correlated to semidesert range sites in Utah. <br />Diagnostic horizons and features recognized in this pedon are: <br />Ochric epipedon - from 0 to 3 inches (A horizon). <br />Cambic horizon - from 3 to 16 inches (Bw horizon). <br />The Bk horizon is assumed to have too little carbonate to be a calcic horizon. <br />In December 1994 the classification was changed from Ustollic Camborthids to Ustic Haplocambids. <br />(Revised June 2008) Attachment 2.04.9-3-9
